Merit Brass K612-1202 Pipe Reducer 3/4x1/8 316 Ss Fnpt

Product Description

The MERIT BRASS K612-1202 is a threaded pipe reducer fitting designed to connect pipe runs of different diameters in plumbing, industrial, and mechanical piping systems. It transitions from a 3/4-inch female NPT inlet to a 1/8-inch female NPT outlet, allowing a line reduction within a single compact fitting. Constructed from 316 stainless steel, this reducer delivers strong corrosion resistance in demanding environments, including exposure to chemicals, salt water, and elevated moisture. The fitting carries a 150 psi pressure rating and conforms to ISO standards. Licensed plumbers and pipefitters are the primary installers.

This reducer is suited for residential and light commercial piping applications where a threaded inline diameter reduction is required. Typical uses include instrument lines, hydraulic systems, compressed air headers, and process piping where stainless steel material compatibility and corrosion resistance are priorities. The FNPT x FNPT connection on both ends accepts standard tapered pipe threads, making it straightforward to integrate into existing threaded systems without specialty tooling.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet and chemically active environments
• 3/4-inch to 1/8-inch reduction in a single threaded fitting
• FNPT x FNPT end connections accept standard tapered pipe threads
• 150 psi pressure rating suitable for low-pressure process and instrument lines
• ISO-conforming design for consistent thread form and dimensional accuracy
• Compact 1.5-inch body length for use in tight installation spaces

Compatibility

Designed as an OEM-style threaded replacement reducer for systems using 3/4-inch to 1/8-inch FNPT connections in stainless steel piping assemblies.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter in accordance with applicable IPC or IFGC code requirements. Shut off system pressure and depressurize the line fully before removing or installing any threaded fitting. Apply an appropriate thread sealant or PTFE tape rated for the service media to all male threads before assembly. Do not over-torque stainless steel fittings, as galling can permanently seize the threads.
